Our program will convert a weight expressed in pounds into kilograms a. Our input is the weight in pounds b. Our output is the weight in kilograms c. We also know that Kilograms Pounds /2.2 Let's take another look at the program which converts pounds to kilograms. Since a weight cannot be a negative number, our program should not accept a negative number as a valid weight. Let's rewrite th e program to print an error message if the weight entered in pounds is negative. 2. An Auto Insurance Program Example - Write a program to determine the cost of an automobile insurance premium, based on driver's age and the number of accidents that the driver has had. basic insurance charge is $500. There is a surcharge of $100 if the driver is under 25 and an additional surcharge for accidents: of 50 125 225 375 575 6 or moreNo insurance the user for a number and print good if the number is greater than 5 and between 8 & 10 (inclusive) or greater than 33. Otherwise, print bad. Use the logical operators in your if statement.

Answer 1

Please find the code below:

WeightConverter.java

package classes9;

import java.util.Scanner;

public class WeightConverter {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Enter weight in pounds : ");

double weight = sc.nextDouble();

if(weight<0){

System.out.println("Invalid entry!!! Weight cannot be empty.");

}else{

double kilo = weight/2.2;

System.out.printf("Weight %.2f pounds equals to %.2f in kilograms",weight,kilo);

}

sc.close();

}

}

AutoInsurance.java

package classes9;

import java.util.Scanner;

public class AutoInsurance {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Enter your age : ");

double age = sc.nextDouble();

double basicCharge = 500;

if(age<25){

basicCharge+=100;

}

System.out.print("Enter number of accident : ");

int accidentCount = sc.nextInt();

if(accidentCount==1){

basicCharge+=50;

}else if(accidentCount==2){

basicCharge+=125;

}else if(accidentCount==3){

basicCharge+=225;

}else if(accidentCount==4){

basicCharge+=375;

}else if(accidentCount==5){

basicCharge+=575;

}else if(accidentCount>5){

System.out.println("Sorry you are not eligible for insurance");

return ;

}

System.out.println("Your insurance charge is : $"+basicCharge);

sc.close();

}

}

AmIgood.java

package classes9;

import java.util.Scanner;

public class AmIgood {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Enter a number : ");

int number = sc.nextInt();

if( ((number>5) &&(number>=8 && number<=10)) || number>33){

System.out.println("Good");

}else{

System.out.println("Bad");

}

sc.close();

}

}

output:
